本数据集为在花寨子荒漠加密观测区测量地表粗糙度数据。\n
\n测量内容：\n
\n（1）2008年5月24日进行了ASAR与MODIS同步观测，在花寨子荒漠样地2开展了地表粗糙度的测量。\n
\n（2）2008年5月30日进行了机载红外广角双模式成像仪（WiDAS）飞行同步，在花寨子荒漠样地1测量了地表粗糙度。\n
\n地表粗糙度采用照相法测量粗糙度。测量仪器为中国科学院寒区旱区环境与工程研究所自制的粗糙度板、数码相机和罗盘。测量对象为花寨子荒漠样地1和花寨子荒漠样地2。沿着样地两条对角线等间隔采样测量，每次测量包括东西向和南北向，每张照片上具有测量标示。

\nMeasurement content:\n
\n（ 1) The simultaneous observation of ASAR and MODIS was carried out on May 24, 2008, and the surface roughness was measured in huazhaizi desert sample plot 2.\n
\n（ 2) The flight synchronization of airborne infrared wide-angle dual-mode imager (widas) was carried out on May 30, 2008, and the surface roughness was measured in huazhaizi desert sample plot 1.\n
\nThe surface roughness is measured by photographic method. The measuring instruments are the roughness board, digital camera and compass made by the Institute of environment and Engineering in cold and arid areas of Chinese Academy of Sciences. The measured objects are huazhaizi desert sample 1 and huazhaizi desert sample 2. Sample and measure at equal intervals along the two diagonal lines of the sample plot. Each measurement includes east-west and North-South directions, and each photo has measurement marks.\n
